After I installed the latest Mac update (Big Sur 11.5.2) my Razer Basilisk V2 mouse is no longer being detected. The light in the mouse turns white, but the mouse isn't working.

I have reset SRAM and PRAM, which didn't work. I have installed bootcamp, because I have assumed that this is a software error, and it didn't work there as well. The USB device was detected, not as the Razer device it is, but it was detected. The following error was visible:

This device cannot start. (Code 10)

I still think, that this is a software problem and that there is some sort of corrupt information on my system. Unfortunately I do not have a second PC or MacBook to test the Razer mouse itself. Connecting my lightning power cable or my iPhone to the USB-Ports works though!

Is there a way to make my mouse work again? Maybe some sort of software or the possibility to remove corrupt files?

  • First thing I would check is if Razor have an update for their drivers. Also, what did you update from and was it working correctly then?
